You will soon be able to wander a medieval kingdom of fantasy and legend on its way for the summer school holidays - but beware the dragons.

In this giant kingdom you'll also find a wizard and princess, and a brave knight who will no doubt fight the dragon.

But these large-scale sculptures have actually been constructed from a popular children's toy.

Visitors can meet characters at Lincoln Castle including Princess Orra, Abbra the Wizard and Sir Studley the Knight, and marvel at the huge dragon standing over four metres tall and five metres long, with glowing eyes, realistic sound effects and dragon fire breath.

In total 19 models are on their way, made from a staggering 1,739,200 LEGO bricks.

Everyone heading along will also see Shrike the Griffin, Brilliance the Unicorn, Torry the Huntswoman and much more.
